The FOTA file was successfully downloaded, but it is not applied after the restart

The FOTA file was downloaded successfully, but it is not being applied after the restart. After every reset, the device repeatedly shows: ‘FOTA ready – begin power reset’, followed by another reset

Hi,
Excuse me, are you using USB for DFOTA?
If so, the upgrade process cannot be seen on the USB end. After the download is completed, it will take some time to install. You can see the upgrade details using the serial port.
